The effects of cell extracts and supernatants of Lactobacillus spp. and Corynebacterium spp. on catalase activity and growth of Staphylococcus aureus 6538 P were studied. Intra- and extracellular metabolites of lactobacilli and corynebacteria inhibited catalase activity of S. aureus 6538 P. The growth of S. aureus 6538 P decreased after incubation with lactobacillus metabolites. The inhibitory effect of intra- and extracellular metabolites of lactobacilli and corynebacteria on catalase activity of S. aureus is a possible pathway of microbial interrelations responsible for the formation and/or development of microbial biocenoses.

This paper developed an efficient microbial activator formula and conducted an in-depth study on its efficacy and mechanism in promoting the degradation of petroleum hydrocarbons in oil-contaminated soil. A 60-day microbial remediation experiment conducted on oily soil revealed that the microbial activators significantly boosted the activities of dehydrogenase and catalase, subsequently speeding up the degradation of petroleum hydrocarbons in the soil. The overall degradation rate reached as high as 71.

Growing evidence suggests that plant compounds are emerging as a tremendous source for slowing the onset and progression of Alzheimer's disease (AD). Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid with some hypoglycemic, anticancer, and antiinflammatory activities. However, the pharmacological effects of UNA on AD are still unknown.

Chemotherapy-induced cognitive impairment, referred to as "chemobrain", is widely acknowledged as a significant adverse effect of cancer therapy. Paclitaxel, a chemotherapeutic drug, has been reported to cause cognitive impairment clinically and in animal models. However, the precise mechanisms are not fully understood.

This study was planned and executed to investigate the effects of two levels of compound toxin binder (CTB) on growth performance, serum biochemistry, antioxidant status, intestinal morphology, and the ileal selected microflora population in broiler chickens. A total of 240 one-day-old Ross 308 broiler chickens were divided into four treatments and six replicates (10 chickens per replicate). Experimental groups included; 1, negative control (NC; no aflatoxins (AFs) and no additives); 2, positive control (PC; 490 µg/kg AFs); 3, low levels of compound toxin binder (LCTB), PC + 1 g/kg available CTB (Navacidox); and 4, high levels of compound toxin binder (HCTB), PC + 2 g/kg Navacidox.

The research sought to assess the therapeutic impact of resveratrol by biochemical, immunohistochemical, and histopathological analyses in a TiO-induced liver fibrosis model. Titanium dioxide (100 mg/kg body weight) was delivered for 15 days to induce liver fibrosis, either alone or in conjunction with resveratrol (30 mg/kg body weight) therapy for the same duration. Resveratrol has been identified as a crucial therapeutic drug that provides an alternative treatment method for TiO-induced liver fibrosis by mitigating inflammation, oxidative stress, and the expressions of α-SMA and 8-OHdG.
